I have created an ASP page to display records for auditor review and response. The page consists of two repeaters that display 5 rows from a database at a time. for each row displayed, a RadioButtonList, containing two buttons is attached. If the second button is selected, an input text box is displayed to allow auditor comments.
My situation is that I cannot find a way to identify which row is being selected? When I select the Button that should enable the text box, I'm receiving the following error:
"Object reference not set to an instance of an object"
I'm just starting out in ASP coding and would like to know what I'm not doing right?

My problem is I get an "Object reference not set to an instance of an object." error at runtime on the line "ddl2.SelectedValue = cat1". Ironically I got this from an example on the internet and the only difference is my Cat1 varible which has the correct value at runtime.

In the same Code behind file I have:
// This works
Label lblTopNavBarInfo = (Label)Master.FindControl("lblTopNavBarInfo");
lblTopNavBarInfo.Text = "Currently Serving: + FirstName + " " + LastName ;
// This compiles but throws an error in the browser
LinkButton lnkBtnProductsOwned = (LinkButton)LeftNav_CustServ1.FindControl("ProductsOwned"); // The Control is visible
lnkBtnProductsOwned.Enabled = false; // Error: Object reference not set to an instance of an object.

I am trying to implement the code URL...I have a database table with Integer type.Here is the running code line: Code in GridView:
<asp:TemplateField HeaderText="RegionNavn">
<ItemTemplate>
<%# Eval("RegionNavn")%>
</ItemTemplate>
<EditItemTemplate>
<asp:Label ID="lblRegionNavn" runat="server" Text='<%# Eval("RegionNavn")%>' Visible = "false"></asp:Label>
[code]...
On Edit Click, the DropDownList in the GridView brings the previously selected value.On Update Click, the error is: "System.FormatException: Input string was not in a correct format."
dCmd.Parameters.Add("@KystverketRegionID", SqlDbType.Int).Value = int.Parse(ddKystverketRegionID.SelectedValue);
When I use the following code:
ddlRegionNavn.DataTextField = "RegionNavn";
ddlRegionNavn.DataValueField = "RegionID"; // from RegionNavn to RegionID
On Edit Click, the DropDownList values in the GridView is not firing and the following error shows.Object reference not set to an instance of an object. How to implement the code when having a value of type Int ?

I have a dropdownlist attached to a cell when edit is selected. I am using the following code to populate the drop down list with the value that is on the row.
dlBU.Items.FindByValue((e.Row.FindControl("lblBU") as Label).Text).Selected = true;
This works famously when I have a value in the cell. It fails when the cell has not yet been populated. Is there an if then clause that if the value of e.Row.findcontrol("lblBU") is null no default value?

in my default.aspx page i have a dropdown List and a textbox with a submit button below that there are 2 listbox... and the dropdown list holds the names of the listbox
my logic here is to select an item from the dropdown list and put some text in the text box and submit the form which will add an item to the listbox selected.. but when i do this i get an error saying Object reference not set to an instance of an object. i tried to figure out the problem and found that when i remove the reference to the Site Master Page it works fine and when i undo and apply my reference back to the Site Master Page i get the same error.
